Conventional colonoscopy is currently the method of choice for colorectal cancer (CRC) screeningdue to its ability to detect and remove precancerous polyps. However, this screening modality is not widely accepted because of its invasiveness, cost, need for sedation, and limited capacity. Attempts were made to find new non-invasive methods for CRC screening. The ideal technology would be a disposable, skill-independent, anesthesia-free, self-propelling, self-navigating miniaturized endoscopic device that can move along the entire length of the colon while transmitting video pictures of the colonic mucosa, and one that has a therapeutic option as well. These new technologies have the potential advantages of higher adherence rates to screening and more widespread availability. Over the years, different prototypes of self-propelled devices have been described. The vast majority of these have not reached the stage of clinical application. This chapter describes those self-propelled devices that have reached the stage of clinical trials and discusses the initial results of these studies.
